Work table

ABSTRACT

The invention relates to a work table comprising a worktop for assembling tools. The inventive work table is characterized in that the worktop has at least one or more recesses, one worktop segment each being disposed in every recess and being mounted in the worktop so as to be rotatable about an axis of rotation that extends in parallel to the upper surface of the worktop; the work table comprises devices for locking the worktop segment in the worktop; the worktop segment, in the area of the axis of rotation, is mounted in two guides configured on the work table; and the worktop segment can be displaced alone or together with the axis of rotation along the guides in parallel to the upper surface of the worktop.

The invention relates to a work table. It relates in particular to awork table for the workshop area.

Work tables in the workshop area, but also in all other areas in whichwork tables are used, are utilized on the one hand for receiving thetool and/or the working means, and on the other hand for receivingand/or setting down the material to be worked. In the workshop area, thetools are frequently securely mounted on the worktop of the work table.However, the mounting of tools on the work table inevitably leads to areduction in the surface of the work table that is then available forthe materials to be worked.

Moreover, a plurality of different tools, for example woodworking,metalworking or other machining tools or equipment, are required inparticular in workshops, so that an appropriately large working surfaceis required on the one hand for the tools alone, and on the other handfor the materials to be worked. The working surface is not usuallyadequate for this reason.

A solution to this problem often involves the use of smaller, and thusmore mobile variants of the individual tools. Tools of this kind aresubject to performance limitations, however, so that their use is notactually possible in the professional area.

Previously disclosed by DE 41 06 073 C2 is a work table, which exhibitsa recess in a worktop, in which recess different tools arranged on aworktop segment can be mounted or added by means of a rotatingmechanism. Although a much more favorable utilization of the surface ofa work table is achieved in this way, the associated cost iscomparatively high, namely when the envisaged machine magazine isembodied as a rotary magazine. Consideration must also be given to thefact that only a single working machine can be brought into the plane ofthe worktop of the work table in each case.

A further solution involves mounting only the tool that is required ineach case on the work table. The replacement of a tool in this case istime-consuming, however, so that a dedicated work table is required as ageneral rule for each tool.

The object of the invention is to overcome the disadvantages associatedwith the prior art. The intention in particular is to propose a worktable which permits the use of two or more tools on a small worksurface, compared with the prior art.

This object is achieved by the characterizing features of claim 1.Appropriate embodiments can be appreciated from the characterizingfeatures of claims 2 to 12.

A work table with a worktop for mounting tools is proposed in accordancewith the invention, wherein

-   the worktop exhibits at least one or a plurality of recesses, and    arranged in each case in each recess is a worktop segment that is    rotatably mounted in the worktop about an axis of rotation running    parallel with the upper surface of the worktop;-   the work table comprises devices for locking the worktop segment in    the worktop;-   the worktop segment in the area of the axis of rotation is mounted    in each case in two guides embodied on the work table; and-   the worktop segment is capable of displacement alone or with the    axis of rotation along the guides parallel with the upper surface of    the worktop.

In a first embodiment of the work table in accordance with theinvention, in the locked state the upper surface of the worktop segmentand the upper surface of the worktop together form a single plane. Inthis embodiment, the axis of rotation is arranged in the plane of theworktop.

The work table in accordance with the invention thus makes it possiblefor a (first) tool, which is attached to the upper surface of theworktop segment, to be moved by causing it to rotate through 180° aboutthe axis of rotation to a position under the work table.

Through this rotating movement, the previous upper surface of theworktop segment becomes the under surface, and vice versa. The externalsurface of the worktop segment, which is then rotated upwards, can thenbe utilized depending on the requirements of the user. If no additiontool is mounted on this external surface, it is available as anunobstructed work surface. By further rotation of the worktop segment,the (first) tool can be moved upwards, as a result of which it is onceagain ready for use.

The “folding down” of tools in this way thus permits a clearly improvedutilization of the space available. If, for example, a clear worksurface is required to enable constructional drawings to be laid out,all of the tools can be rotated downwards, wherein the previous, clearunder surfaces of the worktop segments are rotated upwards. The toolsare removed from the work surface of the work table in this way, so thatthe entire surface of the work table can now be used freely.

The work table in accordance with the invention permits significantlybetter utilization of the space available. This also offers advantagesin conjunction with the installation of extraction systems, which,because of the more compact arrangement of the tools, only need toexhibit a small effective area. Furthermore, the work table inaccordance with the invention is capable, if the table legs are offolding execution, of being transported more easily in vehicles, giventhat on-site use is otherwise only possible with tools that are capableof being transported separately.

In the first embodiment, the devices for locking the worktop segment inthe worktop are preferably executed as locking levers, wherein

-   at least two locking levers are provided for every worktop segment,    and-   every locking lever exhibits a first position and a second position,    in which first position the worktop segment is capable of rotating    in the work table (unlocked state of the worktop segment), and in    which second position the worktop segment is locked in the worktop    (locked state of the worktop segment).

A first edge of the worktop segment in the locked state is appropriatelypart of an outer edge of the worktop. In this case, the recesses areexecuted with a U-shaped form in the worktop, so that larger tools,which are attached to the worktop segment, can also readily be rotatedupwards or downwards. This would not necessarily be the case for squareor rectangular recesses, i.e. recesses that are arranged in the worktopwithout a common outer edge.

The first edge of the worktop segment preferably exhibits a firstgroove, wherein the second edge of the worktop segment lying oppositethis first edge exhibits a second groove, and the worktop exhibits aweb, which is complementary to the first and second grooves. The web inthis case is executed on the edge of the worktop, which in the lockedstate of the worktop segment is adjacent to the second edge of theworktop segment, and in the locked state engages in the second groove,whereas in the unlocked state the engagement between the web and thesecond groove is released.

The axis of rotation must not necessarily be executed as a transcurrentaxis. On the contrary, the two ends of the axis of rotation arepreferably executed as bolts, which on the one hand are anchored in theworktop segment and on the other hand are supported in the guides.

In a second embodiment of the present invention, the upper surface ofthe worktop segment in the locked state is arranged parallel with theupper surface of the worktop, wherein

-   the worktop segment is present either in a first plane or in a    second plane;-   the second plane runs below the first plane in relation to the    height of the work table;-   the upper surface of the worktop segment and the upper surface of    the worktop form a plane if the worktop segment is present in the    first plane; and-   the upper surface of the worktop segment is present below the upper    surface of the worktop in relation to the height of the work table    if the worktop segment is present in the second plane.

In this embodiment, the axis of rotation is arranged beneath the firstplane of the worktop. The guides, in which the axis of rotation ismounted, are preferably executed as so-called indexable blocks, whichare arranged on the under surface of the worktop or on the work table inthe area of the stand elements underneath the worktop.

The distance between the first plane and the second plane is preferablyvariable. This is preferably achieved by displacing the axis of rotationrunning parallel with the surface of the worktop vertically in relationto the worktop. The indexable blocks, in which the guides are present,are preferably displaced upwards or downwards in addition, wherein theindexable blocks can be moved upwards or downwards for this purpose, forexample, along a screw thread.

This second embodiment has the advantage that the worktop segment iscapable of being locked at different heights. Larger items of equipment,for example, which would otherwise require to be mounted on a lowertable, can also be positioned readily in this way on the work table inaccordance with the invention.

Similarly, as in the first embodiment, the devices for locking theworktop segment in the worktop are embodied as locking levers, wherein,however at least four locking levers are provided for each worktopsegment;

-   two first locking levers are arranged in the first plane, and two    second locking levers are arranged in the second plane;-   each working lever exhibits a first position and a second position,    in which first position the worktop segment is capable of rotating    in the work table (unlocked state of the worktop segment), and in    which second position the worktop segment is capable of being locked    to the work table (locked state of the worktop segment); and-   the worktop segment is either locked in the first plane by means of    the first locking lever, or is locked in the second plane by means    of the second locking lever.

The second locking levers are appropriately secured to the work table bymeans of a first securing element. These first securing elements andwith them the second locking levers should be capable of being foldedunder the table, wherein they can be unfolded if they are required forthe purpose of locking the worktop segment in the second plane.

If the distance between the first plane and the second plane changes,the distance between the first securing element and the under surface ofthe worktop must also be changed, so that the second locking levers arepresent in the second plane.

A first edge of the worktop segment in the locked state in the firstplane preferably forms a part of the outer edge of the worktop.

The first edge of the worktop segment appropriately exhibits a firstgroove, wherein the second edge of the worktop segment lying oppositethis first edge exhibits a second groove, and the worktop exhibits afirst web which is complementary to the first groove and the secondgroove,

-   wherein the first web is arranged in the edge of the worktop, which,    when the worktop segment is in the first plane, in the locked state    of the worktop segment, is adjacent to the second edge of the    worktop segment, and wherein-   the web engages in the second groove in the locked state, when the    worktop segment is in the first plane, and in the unlocked state the    engagement between the web and the second groove is released.

Furthermore, the work table in this case should exhibit for each worktopsegment a second securing element with a second web, which runs parallelwith the first web in the second plane, so that the first groove engagesin the second web after rotating the worktop segment through 180°.

Thus, when the worktop segment is present in the second plane, in thelocked state of the worktop segment, the second web is adjacent to thesecond edge of the worktop segment, wherein, in the locked state, thesecond web, if the worktop segment is present in the second plane,engages in the first groove, and in the unlocked state the engagementbetween the second web and the first groove is released.

If the distance between the first plane and the second plane changes,the distance between the second securing element and the under surfaceof the worktop must also be changed, so that the second web is presentin the second plane.

The axis of rotation must not necessarily be executed as a transcurrentaxis. On the contrary, the two ends of the axis of rotation arepreferably executed as bolts, which on the one hand are anchored in theworktop segment and on the other hand are supported in the guides, forexample the indexable blocks.

A plurality of worktop segments is preferably provided in bothembodiments. The length and width of the worktop segments may differ onefrom the other. Furthermore, both worktop segments according to thefirst embodiment and segments of the second embodiment can be combinedin a single work table.

In both embodiments, each worktop segment preferably exhibits fourlocking grooves for the purpose of locking the same, wherein in thelocked state two locking levers in each case are in engagement with thelocking grooves of the worktop segment. The locking levers which areprovided in the first embodiment, and the locking levers which areprovided in the first plane of the second embodiment, are preferably letinto the outer edge of the worktop. The grooves of the worktop segmentsare designed in such a way in this case that the part of the lockinglever that is present in the grooves can be pulled out of the grooves ofthe worktop segment in each case in the locked state, so that theengagement of the locking levers in the locking grooves is released andthe worktop segment is then capable of being rotated.

The locking grooves are appropriately executed on the first edge and thesecond edge of the worktop segment, wherein the first groove and thesecond groove are able to graduate into the locking groove. In the caseof the first embodiment, the locking lever is initially in engagementwith both of the grooves on the first edge in the locked state. In orderto rotate the worktop segment through 180°, the locking lever isreleased, the rotation is performed, and the locking lever is thenlocked in the second edge, which is now a part of the outer edge of theworktop. This process is reversible.

In the case of the second embodiment, both of the first locking levers,when the worktop segment is in the first plane, are initially inengagement with both of the grooves on the first edge in the lockedstate. In order to rotate the worktop segment through 180°, the lockinglevers are released, the rotation is performed, and both of the secondlocking levers are then locked in the second edge, which is now a partof the outer edge of the worktop. This process is reversible.

The work table 1 depicted in FIGS. 1 and 4 to 6, exhibits a worktop 2,which is supported on table legs 3. Recesses 4 (FIG. 2), in whichworktop segments 5 are arranged, are executed in the table top. Theworktop segments are arranged in the first plane in each case in FIG. 1,so that the upper surface of the worktop segments 5 and the worktop 2constitute a single plane. Second locking levers 7 are attached to theunder surface of the worktop 2 via first securing elements 20, which,when all the worktop segments 5 are in the first plane, are foldedinwards. The second locking levers 7 can be folded outwards (indicatedby broken lines) when the worktop segment 5.2 is to be rotated into thesecond plane. For this purpose, the worktop segment 5.2 is caused torotate on an axis of rotation, which is supported in the indexableblocks 8. The indexable blocks 8 are also attached to the under surfaceof the worktop 2.

Skids 9 and rollers 10 are executed at the lower end of the table legs3. The rollers 10 can be extended and retracted via a folding mechanism11. With the rollers in the extended state, the work table can be movedand thus readily displaced as a whole.

The worktop 2 depicted in FIG. 2 exhibits first webs 12, guides 14 andlocking grooves 17 in the area of the recesses. In the locked state, theweb 12 engages in the second groove 16 (FIG. 3, FIG. 8, FIG. 9) when theworktop 2 is in the first plane. In this way, the worktop 2 is lockedadditionally to the locking devices in its position in each case.Indexable blocks 8 and second securing elements 21 with second webs 13,by means of which vertically adjustable worktop segments in accordancewith the second embodiment of the present invention can be realized, areexecuted in addition on the under surface of the worktop 2. The firstgroove 16 engages in the second webs when the worktop segment 5.2 is inthe second plane in the locked state.

The first 20 and the second 21 securing elements and the indexableblocks 8 are each secured to the under surface of the worktop 2 viathreaded rods, so that they can be screwed upwards or downwards.

The worktop segments 5 can be of any desired design, provided that theyexhibit the characteristics described above, they completely occupy therecesses 4 in the worktop 2 in particular, and they exhibit the proposedgrooves and axes of rotation. According to FIG. 3, worktop segments 5are constructed in three layers in an advantageous variant: with a firstcover plate 22, to the upper surface of which a frame 23 is applied. Thesurface of the frame 23 facing away from the cover plate 22 is coveredby a second cover plate 24. The necessary first and second grooves canbe readily executed through this construction of the worktop segments,in that the frame 23 in relation to the first and second edge of thework place segment 5 is executed offset towards the interior.

Two indexable blocks 8 and a second securing element 21 with a secondweb 13 are executed for the worktop segments 5.2 in accordance with thesecond embodiment in each case on the under surface of the worktop 2.The first securing element 21 is arranged in a U-shaped recess 4 forthis purpose at the base of the “U”, whereas an indexable block 3 isprovided in each case at each leg of the “U” (see in particular FIG. 7).Devices of this kind are not required for worktop segments 5.1 inaccordance with the second embodiment, wherein the worktop segments 5.1are not vertically adjustable, but are only rotatable.

A worktop segment 5.1 can be rotated as follows in its recess 4 in theworktop 2 (FIG. 8):

1. Locked position: In FIG. 8 a the worktop segment 5.1 is locked in therecess 4, wherein the first web 12 of the worktop 2 is in engagementwith the groove 16. A tool 27 is secured on the under surface of theworktop segment 5.1. The upper surface of the worktop segment 5.1 andthe upper surface of the worktop 2 form a plane. The first lockinglevers 6 engage in the locking grooves 17 of the worktop segment 5.1,which are executed in the groove 15. For the purpose of rotating theworktop segment 5.1, the locking levers 6 are released and the worktopsegment 5.1 is pulled in the direction of the arrow, wherein theengagement between the first web 12 and the groove 15 is released.

2. Rotation position: The state illustrated in FIG. 8 b, in which theoriginal position of the tool is represented by broken lines, isachieved by pulling. Pulling also causes the axis of rotation (realizedby two bolts as a general rule) to be drawn along the guides 14 (FIG. 7)over a segment arc 29 from the locked position into the rotationposition. The segment arc is of arc-shaped embodiment, in order toprevent the undesired return of the worktop segment from the rotationposition into the locked position. Pulling the worktop segment from thelocked position into the rotation position causes the arc of the segmentarc of spring-like execution to be pushed downwards, so that such apositional change can be completed without the expenditure of highforce, although only when at least a certain level of tensile force isutilized.

3. Rotation: In the rotation position, the worktop segment 5.1 isrotated through 180° in the direction of the arrow (FIG. 8 c), whereinthe previous under surface of the worktop segment 5.1 adopts anupward-facing position.

4. Locked position: The rotation position is left by pushing the worktopsegment 5.1 in the direction of the arrow (FIG. 8 d), and the worktopsegment 5.1 again arrives in a locked position, wherein the tool 27 isnow present on the upper surface of the worktop segment 5.1. The firstweb 12 is in engagement with the groove 15 of the worktop segment 5.1,so that a locked position has been achieved. At the same time, pushingin the direction of the arrow causes the axis of rotation to bedisplaced along the guides 14 from the rotation position into the lockedposition on the segment arc 29. The (henceforth) upper surface of theworktop segment 5.1 and the upper surface of the worktop 2 in turn forma plane. The first locking levers 6 engage in the locking grooves 17 ofthe worktop segment 5.1, which are executed in the groove 16.

A further rotation of the worktop segment 5.1 from this position intothe original position is possible without difficulty.

A worktop segment 5.2 can be rotated as follows in its recess 4 in theworktop 2 (FIG. 9):

1. Locked position: In FIG. 9 a the worktop segment 5.2 is locked in therecess 4 in the first plane, wherein the first web 12 of the worktop 2is in engagement with the groove 16. The axis of rotation 28 of theworktop segment 5.2 is supported in indexable blocks 8. The axis ofrotation 28 is rigidly connected to the worktop segment 5.2 via twoflanges 30. Each indexable block 8 exhibits a segment arc 29. The uppersurface of the worktop segment 5.2 and the upper surface of the worktop2 form a plane. The first locking levers 6 engage in the locking grooves17 of the worktop segment 5.2, which are executed in the groove 15. Forthe purpose of rotating the worktop segment 5.2, the worktop segment 5.2is pulled in the direction of the arrow, wherein the engagement betweenthe first web 12 and the groove 16 is released. The second lockinglevers 7 are in a retracted position. They are folded outwards (brokenline) before pulling.

2. Rotation position: The state illustrated in FIG. 9 b is achieved bypulling. Pulling also causes the axis of rotation 28 (realized by twobolts as a general rule) to be drawn along the indexable blocks 8 overthe segment arc 29 from the locked position into the rotation position.The segment arc is of arc-shaped embodiment, in order to prevent theundesired return of the worktop segment from the rotation position intothe locked position. Pulling the worktop segment 5.2 from the lockedposition into the rotation position causes the arc of the segment arc 29of spring-like execution to be pushed downwards, so that such apositional change can be completed without the expenditure of highforce, although only when at least a certain level of tensile force isutilized.

3. Rotation: In the rotation position, the worktop segment 5.2 isrotated through 180° in the direction of the arrow (FIG. 9 c), whereinit moves from the first plane into the second plane, and the previousunder surface of the worktop segment 5.1 now forms the upper surface.

4. Locked position: The rotation position is left by pushing the worktopsegment 5.2 in the direction of the arrow (FIG. 9 d), and the worktopsegment 5.2 once more arrives in a locked position, wherein it is nowpresent on the second plane. The second web 13 is in engagement with thegroove 15 of the worktop segment 5.2, so that a locked position has beenachieved. At the same time, pushing in the direction of the arrow causesthe axis of rotation to be displaced along the indexable blocks 8 fromthe rotation position into the locked position on the segment arc 29.The second locking levers 7 engage in the locking grooves 17 of theworktop segment 5.2, which are executed in the groove 16. A furtherrotation of the worktop segment 5.2 from this position in the secondplane into the position in the first plane is possible withoutdifficulty.

Each of the first and second locking levers is supported in a rotatablefashion on a strut 31 (FIG. 10). The locking lever exhibits a laterallyreversed, integrated sliding block 35 with retaining hooks 32, ontowhich pressure is exerted by means of a spring 33. The retaining hook 32is in engagement with a retaining plate 34, which is attached to thelocking groove 17 by one external leg. The spring 33 prevents theundesired release of the retaining hook 32 from the retaining plate 34and thus the locking lever from the locking groove 17. The locking leveris withdrawn from the locking groove 17 in order to release the lockingbetween the worktop segment 5 and the worktop 2, wherein, by pushing thesliding block 35, the retaining hook 32 moves out of engagement with theretaining plate 34. In order to lock the worktop segments 5 to theworktop 2, the locking lever 7 is pushed into the locking groove 17,wherein the retaining hook 32 enters into engagement with the retainingplate 34.
